15312 Foundations Of Programming Languages 2021 Jun 2026

The curriculum of 15-312 is built around several foundational concepts developed by leading computer scientists, most notably Professor Robert Harper. Abstract Syntax vs. Concrete Syntax

These judgments are proven using , written as:

(Note: Schedule is based on a past offering and is subject to change; PFPL stands for "Practical Foundations for Programming Languages," the course textbook.)

The evaluation state of a program represented as a data structure. Understanding continuations unlocks deep control flows like exceptions, coroutines, and threads.

Understanding type systems allows engineers to leverage compilers to catch critical bugs at compile-time rather than in production. 15312 foundations of programming languages

Upon completing 15-312, students are expected to master a powerful set of concepts and skills:

You might wonder why a software engineer needs this level of mathematical rigor. The benefits are profound:

How compilers and interpreters work. 2. The Evolution of Language Design

Modern hardware is massively multicore. 15-312 explores cost semantics for parallel execution and models concurrent processes. Students learn to formally evaluate the tradeoffs between deterministic parallelism and non-deterministic concurrency. 4. The Standard ML (SML) Ecosystem The curriculum of 15-312 is built around several

15-312 is an advanced undergraduate and graduate-level course that shifts the focus from how to code to how languages work . Instead of learning the syntax of a dozen different languages, students learn the universal mathematical principles that govern all languages.

15-312 scales up from a simple, primitive language to highly complex systems by incrementally introducing advanced language features. Feature Category Specific Concepts Significance Higher-order functions, Continuations

Typically taken after introductory courses like 15-150 (Principles of Functional Programming) and 15-210 (Parallel and Sequential Data Structures). 5. Course Structure (Typical)

The rise of LISP and symbolic AI, which EBSCO highlights for its pioneering interpreter-based evaluation. The benefits are profound: How compilers and interpreters

A well-typed program is either already a final value or it can take a step of evaluation. It never gets "stuck."
